Hand dad a whiskey (3)
I believe the answer is:
paw
'hand' is the definition.
('paw' can be a synonym of 'hand')
'dad a whiskey' is the wordplay.
'dad' becomes 'pa' ('pa' can be a synonym of 'dad').
'a whiskey' becomes 'w' (alpha bravo charlie delta ...).
'pa'+'w'='PAW'
(Other definitions for paw that I've seen before include "Foot of clawed animal" , "Animal foot or hill-billy dad" , "Hand; foot" , "Mammal's foot" , "Manhandle" .)
